Work with Kathy Lindert, Your Favorite Hypnotist, One on One to Quit Smoking for Good. You could be a non-smoker in just one hypnosis session! Your Private Session with her will be approximately 2 hours in length. Kathy Lindert is a fully certified hypnotist for smoking. She will look at where, when, and why you smoke, then help you change how you think about smoking. She won’t treat smoking as an addiction but as an unhealthy behavior that can be changed.
